Well, it's looking like you are doing something wrong
yeap, here it's the confirmation:
[NOTE]: don't mind the 4 before the alphabet, it was to identify which phase was actually used in the game because you find many of them inside the pac files.
I don't know what you did. You was talking about a table you made to view the text, maybe something wrong there, you don't need any table.
while i was writing the answer, i maybe found the problem but i don't know yet what is the right one. I believe that your first tries are been messed up by the space character (0x20).
If you take a look at the 2 fonts you found, you see that there is no empty space before the A.
I believe the real space character to be between the Z and the a (5A-61); you need to try them out.
Anyway: the game accepts ASCII (only the character you see on the small font naturally).
All english letters are there, now you need to try them out and find the rest.
Always look at the font pic, they are probably more or less in sequenze like the pic.
If you need to use a unicode character (the big font you found), you need to put that E3 in front of each character. Here the same as above apply, try, try, try.
I just remember you that like the "space" probably messed up your work, there could be other values that have different effect on the characters that follow so you maybe need to check value by value in some points of your search.
